Aeromotive 66141 BoostWorx Returnless PWM Controller for GM CTS-V Fuel Pump

Vehicle Fitment

• GM Cadillac CTS-V2 fuel pump module and compatible GM OEM fuel pump modules

Fitment Notes

• Application is fuel-module specific rather than tied to a single vehicle model year; verify your OEM fuel module matches the CTS-V2 module or a confirmed compatible variant before purchase
• Compatible with either constant fuel pressure or manifold-referenced (boost-responsive) fuel pressure, depending on whether the included MAP sensor is connected

Features

• Stand-alone, OE-type returnless fuel control system
• Supports constant pressure mode or 1:1 manifold-referenced pressure with the included MAP sensor
• Upgrade-ready: install MAP sensor components now to simplify a future supercharger addition
• Acts like a mechanical fuel pressure regulator, with the ECM calibrated the same way
• No relays or Hobb's switches required
• OEM Delphi/Aptiv connectors and cross-linked polyethylene wiring throughout
• Integrates into the OE ECM, keeping factory safety systems functional
• UL94-rated components used throughout

Specifications

• Operating Voltage: 10-22V (compatible with voltage boosters)
• Fuel Pressure Mode: Constant or manifold-referenced (1:1 with boost)
• Compatible Fuel Module: GM CTS-V2 and compatible GM OEM modules
• Over-temperature shutdown with automatic reset
• Short-circuit protection with automatic reset

Included Components

• 1x BoostWorx Returnless PWM Controller
• 1x MAP Sensor and Mounting Hardware
• Wiring Harness with OEM-style Sealed Connectors

Product Description

The Aeromotive 66141 is a stand-alone returnless PWM fuel pump controller built for the GM CTS-V2 fuel pump module and compatible OEM modules. It replaces the need for a traditional return-style regulator and return line by electronically managing pump speed and fuel pressure directly, whether that pressure needs to stay constant or track boost 1:1 through the included MAP sensor.

Leaving the MAP sensor disconnected keeps the system in simple constant-pressure mode, which also makes it straightforward to add manifold-referenced, boost-responsive control later if a supercharger gets added down the line - the hardware is already in place, so the upgrade path doesn't require re-wiring the core system.

This kit suits CTS-V builders and swap applications using a CTS-V2 fuel module who want a clean, electronically controlled fuel system without return lines or a separate mechanical regulator, while retaining OE-style low-fuel-level performance.
